Which Tesla models will be able to use the new FSD? The details
The FSD system is starting to arrive in Europe, but not all Teslas will be able to use it. The hardware makes the difference
Autonomous driving is no longer a distant promise; it's starting to take shape in Europe. Tesla has already taken the first step with its FSD system, which began rolling out in the Netherlands, and with that, a key question has arisen among users. Not all of the brand's cars are ready to embrace this new stage.

Expectations were high, especially among those who had already paid for this feature some time ago.

However, the reality is much more technical than many imagined. Simply having purchased the option isn't enough; the real filter lies in the hardware each vehicle uses.
The decisive factor is the hardware
The FSD system in its latest version is only available, for now, in models that incorporate what's called Hardware 4. This component is responsible for processing all the information received from cameras and sensors and is key to running the system's artificial intelligence.
Tesla began including this hardware in its cars in 2023 in the United States and China, and later in Europe. If someone wants to know if their vehicle is compatible, they can check it directly on the car's screen, within the software section.
The brand's strategy aims to move forward first with the newest models. This is no small decision, because the system's performance depends largely on the vehicle's processing power.
Older models are on hold.
For those who drive Teslas manufactured between 2019 and 2023 with Hardware 3, the outlook is more uncertain. These cars can use FSD in the United States, but with a lighter version of the software.
The possibility of physically upgrading these vehicles to the new hardware was an idea that circulated at the time, even mentioned by Elon Musk. However, everything indicates that this option is no longer on the table.
The reason is simple.
Hardware 3 doesn't have enough power to run the most advanced version of the system. The company itself acknowledges this and is working on an alternative. Ashok Elluswamy, head of software and artificial intelligence, explained that "once version 14 is completely finished, the company plans to work on a lighter version." This would be the solution to prevent these models from being completely left out. Europe imposes stricter rules. Beyond the technical aspects, the European context adds another layer of complexity. Regulations are more demanding than in the United States and require each advancement to undergo more rigorous reviews. Dutch authorities make this clear: "The Dutch-European version of the fully autonomous driving software will not be exactly comparable to the US version due to differences in regulatory processes." Furthermore, they warn that there will be “strict monitoring of driver attention to the road.”
This implies that even compatible models could receive limited or adapted features depending on local laws.
What happens to FSD when selling the car?
Another point of concern relates to resale. Not all buyers of a used Tesla will automatically inherit FSD.
If the system was active via a monthly subscription, the benefit is not transferred. The new owner will have to subscribe to it themselves.
However, if FSD was purchased outright, it remains associated with the vehicle, unless the owner previously transferred it to another Tesla under a specific promotion.
